resternotomy
Surgical reopening of a previously divided sternum, typically for bleeding control or repeat cardiac procedures.
Full Definition
Resternotomy is the surgical procedure of reopening a sternum that was previously divided during cardiac surgery, most commonly performed for postoperative bleeding requiring exploration or for subsequent cardiac operations. The procedure carries increased risks due to scar tissue formation, potential cardiac adhesions, and proximity of the heart to the sternum. Resternotomy may be performed emergently in the ICU for life-threatening bleeding or electively in the operating room for planned repeat procedures, requiring careful dissection to avoid cardiac injury.
Usage
Usage note: Specify whether emergency or elective to convey clinical urgency.
